Since this ancient thread was revived, I will point out that my new 2017 EX feels like it is running quite lean at low rpms. Not an actual sputter as others reported with earlier bikes, but it doesn’t “fuel” cleanly or with linearity. I don’t know if this is a result of the retarded cam timing on cylinders 1 and 2, or if it just running lean. Either way it’s not ideal.
